f: Farmed—The soil surface has been me�hanically or physically altered for production of crops, <br /> but hydrophytes will become reestablished if farming is discontinued. <br /> h: Diked/Impounded—Created or modified by a barrier or dam which purposefully or <br /> unintentionally obstructs the outflow of water. Both man-made and beaver dams are included. <br /> r: Artificial—Refers to substrates classified as Rock Bottom, Unconsolidated Bottom, Rocky Shore, <br /> and Unconsolidated Shore that were emplaced by hurnans, using either natural materials such as <br /> ' dredae spoil or synfhetic materials such as discarded automobiles, tires, or concrete. <br /> s: Spoil—Refers to the placement of spoil materials which have resulted in the establishment of <br /> wetlancl. � • <br /> x: Excavated—Lies within a basin or channel excavated by humans. <br /> 4.2 Wetland Functional Assessment Methodology <br /> In order to compile detailed wetland data and assess the functions for thousands of wetlands in less <br /> than two years based on a short field visit to each wetland, a wetland assessment methodology was <br /> needed that would meet several specific goals: • <br /> 1. The methodology must allow for rapid assessment of wetlands while maximizing the <br /> integrity and value�of the data. <br /> 2. The project was developed with a team of up to 7 wetland scientists conducting field <br /> assessments. To ensure consistency amongst the team, the methodology would have to be <br /> repeatable and minimize reliance on professional judgement. <br /> 3. To ensure accuracy, an assessment methodology was sought to incorporate Geographic <br /> Information System (GIS) analyses of those parameters which are not subjective, could be <br /> analyzed using existing data, and did not require field observation (e.g. upland soils, wetland <br /> soils, property ownership, wetland density, etc...) <br /> 4. Lastly,with such a large number of wetland resources, a system was needed that could <br /> manage all data within a single database and had the capability of dynamically linking with a <br /> GIS. <br /> \\fred\wp123�271D06Uteports�Final Report\WeNand mgmt�lan_dit011503.doc 4-l� <br />
